RHEL/CentOS or Debian for stable deployment

RHEL/CentOS or Debian for stable deployment

[Johan Kröckel]

Hello,
I am not sure whether this is the correct list, but I will try...
I am on the way to deploy new server and already am using
btrfs-volumes. At this point not for root, but in case a stable setup
is possible, this would be cool, too.

I don't want to use vanilla kernel because I like it when someone else
is watching security issues for me.
So the question is:
Which source for the kernel binaries would you use, to get stable
btrfs support together with mentioned service?
I am asking, because I don't know how Red Hat and Debian (Backports
channel) are dealing with backporting new btrfs code to their
distributed kernels.

Thank you

Johan

Have you considered Oracle Linux? We are continually backporting btrfs fixes and enhancements to our Unbreakable Enterprise Kernel releases. On Oracle Linux 6, you would run the UEK Release 3, which is based on 3.8 mainline with upstream fixes. We also provide all security and bug fix errata for free via http://public-yum.oracle.com, so you don’t need to buy support to run Oracle Linux at keep up-to-date.

Cheers,
Avi

Can't remember asking if btrfs is supported on 32 bit kernels?

   I can't speak for Oracle's distribution, but in the general case,
yes, btrfs works on 32 bit systems.

   On the subject of bitness, there's a couple of rough edges with
64-bit kernels and 32-bit userspace. (I think there's still one ioctl
that fails on that configuration, but I've not hit it yet on my test
machine).

btrfs send does not work with 32bit userland and 64bit kernel when I
last tried it a few weeks ago.
Thankfully I had debian, so I was able to upgrade just btrfs-tools to
64bit without upgrading my entire system, and that solved it.

   That's the one I know about and patched some weeks ago :) (it
should be in btrfs-next by now).

We support btrfs on our 32-bit UEK Release 2 (labelled 2.6.39 but it’s actually 3.0 under the hood. Yay userspace issues). However, our latest UEK Release 3 (3.8 both labelled and under-the-hood) is only built for 64-bit and is highly recommended for production btrfs usage. We are no longer back porting mainline fixes into UEK Release 2 because the code has just moved on too far for it to be feasible.

So, while there is a 32-bit kernel with btrfs support, our recommendation is to use the 64-bit kernel on x86_64 hardware for the best experience.

None is really usable for development,  IMHO.

For Development we prefer "Arch Linux", it somewhat more "Bare Linux",
mostly all packages made from unpatched and unmodified "vanilla" sources.

Debian and CentOS are for Development mucht "to matrue", or harder
spoken, much too old.
If a product is ready for deployment, the other Debian / Ubuntu / SuSE /
Fedora / RedHat / CentOS got the Level of the system, which Arch had on
start time of development.

Then we enter package stage and depoy the product to the "stable"
Distributions.

On stable Setup/Server we prefer Debian or Ubuntu.

The Enterprise Distributions (aka. RHEL, SELS, CentOS) are looking to us
sometimes like "software achrchelogy ...
